His grandchildren remembered him as an old man of imposing appearance, with long white hair, talking incessantly of Jacob Boehmen.

Mr.Mills had sons, one of whom edited a Bristol journal exceedingly well, and is said to have made some figure in light literature.

This uncle of Lord Macaulay was a very lively, clever man, full of good stories, of which only one has survived.

Young Mills, while resident in London, had looked in at Rowland Hill's chapel, and had there lost a new hat.

When he reported the misfortune to his father, the old Quaker replied: "John, if thee'd gone to the right place of worship, thee'd have kept thy hat upon thy head." Lord Macaulay was accustomed to say that he got his "joviality" from his mother's family.
If his power of humour was indeed of Quaker origin, he was rather ungrateful in the use to which he sometimes put it.
Mr.Macaulay fell in love with Miss Mills, and obtained her affection in return.
